Abstract: | Non-sampling errors have many different sources, can occur at different stages of the survey and are a result of error contributions of different personnel or agencies Involved in executing the survey. In Interview based surveys,interviewer effectively influences both the response error as well as the response rate. In the present investigation an estimation procedure has been proposed to study the contribution of variance due to response errors as well as non-response errors introduced because of the interviewer. |
